Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 111228, here are decompositions:

11 + 111217 = 111228
17 + 111211 = 111228
37 + 111191 = 111228
41 + 111187 = 111228
79 + 111149 = 111228
101 + 111127 = 111228
107 + 111121 = 111228
109 + 111119 = 111228

Showing the first eight; more decompositions exist.
